45.5 is what percent of 278.95 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 278.95 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 278.95, so we can write it down as 100%=278.95.
4. We know, that x% equals 45.5 of the output value, so we can write it down as x%=45.5.
5. Now we have two simple equations:
1) 100%=278.95
2) x%=45.5
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=278.95/45.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 45.5 is what percent of 278.95

100%/x%=278.95/45.5
(100/x)*x=(278.95/45.5)*x       - we multiply both sides of the equation by x
100=6.1307692307692*x       - we divide both sides of the equation by (6.1307692307692) to get x
100/6.1307692307692=x
16.311166875784=x
x=16.311166875784

now we have:
45.5 is 16.311166875784% of 278.95
